I believe it would be the last one since it is from the national institutes of heath, and that it the most reliable source.
To thrive in a broad range of environments, including soil, water, and eukaryotic cells.
Point (-5,5) lies in Quadrant 2
Here's some notes:
Quadrant 1: (+,+)

Answer:
1, 5, 2, 3, 4
Explanation:
There are several enzymes involved in DNA replication and the step by step process of replication along with enzymes involved is as follows
a) Helicase is the first enzyme to act and it has a very important role in replication. Helicase unwinds the double helix of DNA
b) Single strands binding proteins prevent reattachment of DNA helix
c) Topoisomerase is responsible for relieving or inducing supercoils
d) The primase then lay the starting blocks made from RNA
e) DNA polymerase enzyme III lay the DNA from 5 prime to 3 prime.
f) DNA polymerase enzyme I then do half ladder replication
g) DNA Ligase links all the fragments.
Hence, the correct sequence is 1, 5, 2, 3, 4
Answer:
Both fish and bird embryos possess gill slits and gill arches.
Explanation:
Embryology -- the study of embryos -- is a fundamental area that is correlated to evolution. Together, <u>they have provided evidence that we all evolved from a common ancestor.</u>
This area of study has showed that embryos that look completely different as adults share many similarities during their development. This is the case of numerous species, such as humans and birds and fish and birds.
<u>Both fish and bird embryos possess gill slits and gill arches</u>. However, <u>only fish possess them as adults. Gill slits develop into gill individual openings and gill arches will eventually support these gills. In contrast, adult birds do not possess gills, they are only present during their development.</u> This provides significant insight into the previously mentioned common ancestor theory.
